Another suggested book would be to purchase an additional book (which I did) for extra test prep was "Guide to Passing the Pearson Vue Real Estate Exam 10th EditionTextbook Binding – 2018" by William H.

I ended up moving my portfolio to single family homes that are B class and my situation improved.The other factor here is when you have children in the mix, you just don't have as much extra time.

A couple of extra points interest on $50k for a few months is peanuts compared to the alternative. 

In your market do apartments have any extra expenses (inspections by the city, extra taxes etc?)

I am contemplating taking the time I was spending on school and getting a part time job to generate some extra income.

As they're demoing the roof (and making a HUGE mess around the property, tar and gravel roof+ pine needles being thrown around the yard with no tarps), he comes back and tells me that spacing between the decking is too far apart compared to code, and it's going to be an extra $3,500 to redeck the entire roof (could have told me this when he gave me the initial quote, wasn't hard to see that).

I found that the extra work that is required plus the additional vacancy plus headaches that came with tenants arguing between themselves made it a less than ideal way of investing.

If you thought you needed an extra day, should have put that in initially or amended it along the way to extend.

Be very careful this could possibly not be a squirrel problem but a property management problem, trying to create extra revenue

Stick to your numbers and if it doesn't make sense walk away because trust me, there are plenty of deals out there you just have to put in extra work in this sellers market.
